Description

Technical Field

[0001] This utility model relates to a folding door, specifically a manually openable folding door with a linkage rotation and double guide rail structure, belonging to the field of building door and window technology. Background Technology

[0002] In the existing technology, the folding door structure has the following shortcomings: 1) Some folding doors have complex structures and are inconvenient to open and close, especially when opened and closed manually, it is laborious and difficult to control accurately; 2) The connection and fixing methods of some folding doors are not stable enough, and they are prone to loosening or shaking during use, which affects the user experience and safety; 3) Some folding doors do not have a reasonable functional distinction and connection design for the left and right side doors, resulting in an unsmooth opening and closing process. Utility Model Content

[0003] This utility model proposes a manually openable folding door that uses a linkage rotation and double guide rails. Its purpose is to overcome the above-mentioned shortcomings of the existing technology, simplify the structure, improve the convenience of operation, enhance the stability of the connection, and optimize the smoothness of opening and closing.

[0004] The technical solution of this utility model is a manually operable folding door that employs a linkage rotation and double guide rails. It clearly distinguishes between the active and passive doors, and through a reasonable hinge connection and linkage lock fixation, achieves stable and smooth opening and closing of the folding door. It is suitable for scenarios requiring efficient space utilization and flexible opening and closing, such as large equipment frames, workshops, and large exhibition halls.

[0005] Specifically, the system includes adjacent active and passive doors. The opposite sides of the active and passive doors are fixed to the side frames via a first hinge. Each active and passive door consists of two door panels connected together, with adjacent sides of the two door panels connected by a second hinge. The non-adjacent door panels of the active and passive doors have embedded handles. A door frame assembly is connected between the top and bottom of each side frame. Guide rail assemblies are provided along the length of each door frame assembly, with a break in the middle. The two guide rail assemblies are parallel to each other. The top and bottom ends of the opposite sides of the active and passive door panels are connected to the corresponding guide rail assemblies via sliding rail connectors. The folding door consists of an active door on one side and a passive door on the other side. Both the active and passive doors are fixed to the frame via a first hinge, ensuring a stable connection between the door panels and the frame. Adjacent door panels are connected by a second hinge, allowing for flexible rotation between the door panels. The parallel guide rail assemblies at the top and bottom of the folding door provide guidance and support for the opening and closing of the door. The door is connected to the guide rail assembly via a sliding rail connector. By manually pulling the door, the door moves relative to the guide rail assembly via the sliding rail connector, thus opening and closing the folding door.

[0006] Preferably, the door body adjacent to the active door and the driven door is equipped with a linkage door lock on the side near the driven door. This is used to effectively secure the folding door when it is closed, enhancing security and sealing.

[0007] Preferably, the slide rail connector includes a slide rail connecting block and a connecting rod. One slide rail connecting block is fixedly connected to the door body, and the other slide rail connecting block is slidably connected to the slide rail of the guide rail assembly. The slide rail is installed and fixed to the door frame assembly through a slide rail mounting plate. A guide rail limiting plate is provided at the end of the slide rail. The tops of the two slide rail connecting blocks are respectively rotatably connected to the two ends of the connecting rod through shoulder screws.

[0008] The advantages of this utility model are: A reasonable structural design clearly distinguishes between the active and passive doors. The active door opens first and closes later, making the opening and closing operation more orderly and controllable. The manual opening and closing method is simple and intuitive, requiring no complex power equipment, thus reducing costs and ease of use. Two hinges are used to connect the door body to the frame and between the door body and the frame, ensuring stable connections and flexible rotation, reducing shaking and loosening during use. A linkage door lock is installed on the active door to effectively fix the folding door when closed, improving safety and sealing. A reasonably designed slide rail connector with double guide rails makes the opening and closing process of the folding door smoother, improving the user experience. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0017] like Figure 1 As shown, a manually openable folding door employing linkage rotation and double guide rails includes an active door 12 and a passive door 11 arranged adjacent to each other. The opposite sides of the active door 12 and the passive door 11 are respectively fixed to the side frames 14 by a first hinge 15. Both the active door 12 and the passive door 11 are composed of two door bodies connected together, with adjacent sides of the two door bodies connected by a second hinge 16. A linkage door lock 17 is provided on the side of the active door 12 adjacent to the passive door 11 near the passive door 11. 2. An embedded handle 18 is provided on the door body that is not adjacent to the driven door 11. A door frame assembly is connected between the top and bottom of the two side frames 14 respectively. Guide rail assemblies 13 are provided along the length of the two door frame assemblies respectively. The guide rail assembly 13 is broken in the middle. The two guide rail assemblies 13 are parallel to each other (the top guide rail assembly 13 is used for load bearing, and the bottom guide rail assembly 13 is used for guidance). The top and bottom of the opposite sides of the two door bodies of the active door 12 and the driven door 11 are respectively connected to the corresponding guide rail assembly 13 through slide rail connectors.

[0018] like Figure 2 , 3 As shown, the first hinge 15 and the second hinge 16 are both preferably made of high-strength stainless steel, which can ensure the stability of the connection between the door and the frame 14 and the door and the flexibility of rotation.

[0019] like Figure 4 As shown, the slide rail connector includes a slide rail connecting block 31 and a connecting rod 33. One slide rail connecting block 31 is fixedly connected to the door body, and the other slide rail connecting block 31 is slidably connected to the slide rail 34 of the guide rail assembly 13. The slide rail 34 is installed and fixed to the door frame assembly through the slide rail mounting plate 35. The end of the slide rail 34 is provided with a guide rail limiting plate 36. The tops of the two slide rail connecting blocks 31 are respectively rotatably connected to the two ends of the connecting rod 33 through the shoulder screws 32.

[0020] In the above structure, the folding door consists of an active door 12 on one side and a driven door 11 on the other side. Both the active door 12 and the driven door 11 are fixed to the frame 14 by the first hinge 15, which ensures a stable connection between the door and the frame 14. Adjacent door bodies are connected by a second hinge 16, allowing the door bodies to rotate flexibly.

[0021] The parallel guide rail assembly 13 at the top and bottom of the folding door provides guidance and support for the opening and closing of the door.

[0022] The active door 12 is equipped with a linkage door lock 7, which is used to effectively fix the folding door when it is closed, thereby enhancing security and sealing.

[0023] The door is connected to the guide rail assembly 13 via a slide rail connector. By manually pulling the door, the door moves relative to the guide rail assembly 13 via the slide rail connector, thereby realizing the opening and closing of the folding door.

[0024] During installation, the first hinge 15 is used to install the active door 12 and the driven door 11 onto the frame 14 respectively, and the position of the door is adjusted to ensure the fitting accuracy between the door and the frame 14.

[0025] Connect adjacent door panels using the second hinge 16 and check the rotational flexibility between the door panels.

[0026] Install the top and bottom guide rail assemblies 13, securely fix the guide rail assemblies 13 to the door frame assembly, and adjust the parallelism of the two guide rail assemblies 13.

[0027] Install the slide rail connector and connect it to the active door 12 and the driven door 11 to ensure smooth movement.

[0028] Install a linkage door lock 17 on the active door 12 and adjust the position of the door lock to ensure accurate locking when the folding door is closed.

[0029] When opening and closing manually, Opening process: such as Figure 5 As shown, manually open the linkage lock 17 on the active door 12, grasp the embedded handle 18, and slowly push it outwards to sequentially unfold the active door 12 and the driven door 11 outwards along the top and bottom guide rail assemblies 13. During the unfolding process, the first hinge 15 and the second hinge 16 ensure flexible rotation between the door body and the frame 14, and between the door body, until the folding door is fully opened.

[0030] Closing process: such as Figure 6 As shown, the manual operation of the driving door 12 and the driven door 11 reverses the movement, causing the driving door 12 and the driven door 11 to fold inward. When the folding door is fully closed, the linkage door lock 17 is used to fix the driving door, ensuring that the folding door is in the closed state.

[0031] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
